The process of health services research is rarely examined; attention is usually focused on results and policy implications. Large and small decisions made during the execution of a study, however, can have major impacts on its outcomes. This article describes a project that underwent major changes because of problems discovered in the basic data and threats to the valid interpretation of econometric results uncovered by qualitative case studies. Although the combination of difficulties encountered in this project may be unusual, it is likely that many similar problems and opportunities occur in other empirical studies.
卫生服务研究的过程很少受到审视;人们通常将注意力集中在研究结果和政策影响上。然而,在一项研究的执行过程中做出的大大小小的决策,可能会对其结果产生重大影响。本文描述了一个项目,该项目因基础数据中发现的问题以及定性案例研究揭示的对计量经济学结果有效解释的威胁而经历了重大变化。尽管该项目中遇到的困难组合可能不常见,但在其他实证研究中可能会出现许多类似的问题和机遇。
